I'm conducting a research regarding CDN security, and have noticed that in the following document https://community.akamai.com/docs/DOC-5175
A cipher suite named "ak-akamai-pfs-supported" includes the following:

Those ciphersuites you mention seem to use the OpenSSL name instead of the name from the RFC. You can find a table mapping one to the other here. Note that RSA based ciphersuites certainly don't offer PFS. You'd need DHE or ECDHE (ephemeral-ephemeral key agreement) to have Perfect Forward Secrecy.

In general the OpenSSL name should contain EDH, DHE or ECDHE to provide PFS and neither of the ciphersuites you mention do contain that sequence. So therefore the answer is no, no PFS.
